Abstract

The invention provides an image classification identifying and judging method. The method includes the steps of firstly, acquiring an image, preprocessing the image, denoising the preprocessed image by a top-hat transformation method and enhancing the denoised image by means of histogram equalization; secondly, subjecting the enhanced image to feature extraction to obtain a joint histogram of an N-dimensional vector, and subjecting the N-dimensional vector to dimensionality reduction, wherein the N is a positive integer; thirdly, training the N-dimensional vector subjected to dimensionality reduction by a training set to summarize a classification set, and extracting a feature image by means of classifying or screening.

Description

technical field [0001] The invention relates to the field of computer image recognition, in particular to an image classification recognition judgment method. Background technique [0002] HSI features are color features, based on the HSI color space established from the perspective of human visual perception. H is chroma, which is an attribute describing pure color; S is saturation, which gives a measure of the degree to which a pure color is diluted by white light; I is brightness, which is the brightness response of vision to light stimulation. [0003] The feature extraction method is to quantify the HSI color space according to the following formula, quantize the chroma H into 8 spaces, divide the saturation S into 3 spaces, and divide the brightness I into 3 spaces, that is, the color space is divided into 72 intervals. [0004] Construct a three-dimensional joint histogram of the three components of H, S, and I, but the HSI feature extraction method has no obvious ef...
